Description
Technical field
The present invention relates to a kind of scraper ring.
Background technique
DE 42 36 641 A disclose a kind of scraper ring for internal-combustion engine, this scraper ring is fixed in the groove of the piston that moves in engine cylinder to and fro, and has external face, this external face consistently effect of the expanding unit by the spring-like that arranges in piston groove is pressed towards cylinder wall, wherein, external face is limited by at least two annular regions (working plate), these two annular regions are concentric, has same diameter, and the circumferential clearance of the outer wall by ring comes separately, wherein, each annular region top and inner inclination of external face are used for limiting the surface of tapered profile.
A kind of method and apparatus that is used for making the piston grooved ring of chromium plating has been described in DE 2 324 931 A.The piston ring that can be used as the scraper ring use has two working panels, and working panel has the differently geometrical construction of structure, and is provided with working surface layers.
Described a kind of scraper ring in JP 9-196172A, scraper ring comprises matrix, and this matrix is provided with at least one working panel, and wherein, matrix is connected with the elastic element effect of radially outward effect.Working panel separately is taper in the direction of its free end, and can be provided with in its free end zone different profile (radius, rake etc.).
Obtain a kind of oil ring of assembling by DE 603 02 321 T2, comprise upper rail and bottom rail and spring element, wherein the upper rail of oil ring and bottom rail have exterior circumferential in other words around the surface.The exterior circumferential surface of upper rail has the in other words bucket formula curved surface of asymmetrical tubular type bending, and this surperficial peak is axial in the middle heart setting of axial rail width on bottom side.The exterior circumferential surface of bottom rail has asymmetricly curved surface, and this surface peak is axial in the middle heart setting of axial rail width on bottom side.
By the known a kind of oil ring of EP 1 557 594 A1, this oil ring comprises two working panels, and wherein working panel has the geometric shape that mirror images of each other consist of.
This also is applicable to US 2,657,962 in an identical manner, wherein can identify equally the working panel that mirror images of each other consist of at this.
Scraper ring is used for being down to the oil consumption of explosive motor minimum in the explosive motor field.As can finding out from prior art, known a series of constructive make, these makes are served this target, but not always arbitrarily not effectively.
Summary of the invention
The present invention namely, further forms a kind of scraper ring, so that this scraper ring is about having the frizing mode of improvement working life as follows take following task as the basis.
This task is solved thus, namely, described angle is different, and the free end of working panel extends ground obliquely structure with the angle that can be scheduled to from the zone of grease chamber's side on the direction in the zone of combustion chamber side, wherein, separately transition region from the tilting zone of working panel to arm and construct from arm to matrix rounding ground on the other hand, that is to say on the one hand, is provided with the radius of restriction.
The favourable improvement mode of execution of theme of the present invention is learnt by dependent claims.
Provide a kind of geometric shape by means of scraper ring according to the present invention, this geometric shape is provided with wearing layer (such as chromium layer particularly) by demand.
Therefore, with respect to prior art, except the frizing mode of optimizing, also can bring operation chain and the resultant cost advantage of simplification.
Follow theme of the present invention to bring following advantages:
-linearity the contact of working panel when driving the operation beginning, therefore very high surface pressure and good frizing mode in starting state
-in the free end zone of working panel separately, there is not sharp-pointed seamed edge, may cause the opposing damage of working surface (particularly on cylinder sleeve) of sharp-pointed seamed edge
-structure supporting surface when driving operation, this supporting surface is yet narrow after the operating time more of a specified duration.
The desired tapering of working panel produces positive influences to oil consumption.
Description of drawings
By means of embodiment's object of the present invention shown in the drawings and be described below.
Embodiment
Unique accompanying drawing illustrates scraper ring 1, and this scraper ring 1 in this example is configured to the foundry goods ring.Do not depart from protection domain, can use steel loop here yet.Scraper ring 1 comprises and has radially outer working surface 3 matrix 2 of (forming by two working panels 4,5), internal circumferential face 6, upper side 7 and downside 8.Internal circumferential face 6 comprises groove district 9, and this groove district 9 is used for holding elastic element not shown further.
Because not shown peripheral member, side 7 should should be towards firing chamber B towards the O of grease chamber and side 8.In this example, two working panels 4,5 are implemented on how much in the same manner, wherein, also can imagine the profile of other types.7 set out from the side, be provided with the transition region with radius a, this transition region is transitioned on the diminishing arm 11 in taper ground on the direction of end regions 10.The free end 10 of working panel 4 forms by the transition region with radius b, and and then this transition region is transitioned into direction at firing chamber B and tilts in the zone 12 of (having a down dip).On the end of tilting zone 12, produce the other transition region with radius c, this transition region is transitioned into same taper ground on the upwardly extending arm 13 in the side of matrix 2.Be provided with the other transition region with radius d in the matrix side.In this example, working panel 5 is similar to working panel 4 ground structure, and wherein, this is not enforceable standard.The cone angle towards the O of grease chamber of arm 11 marks with e.The cone angle towards firing chamber B of arm 13 marks with f.Tilting zone 12 is distributed between free end 10 and the arm 13 with angle g.
Therefore, form groove 14 between isolated working panel 4,5, this groove 14 is as oil storage.Herein not shown but can imagine be the radially-arranged oil duct between groove substrate 15 and groove district 9.In this example, working panel 4,5 is implemented with identical height h, but this neither be mandatory essential.The below more at large sets forth the geometrical relationship of scraper ring 1.
A R 0.05mm to 0.20mm
B R 0.05mm to 0.20mm (particularly R 0.10mm to 0.15mm)
C R 0.05mm to 0.20mm
D R 0.05mm to 0.20mm
0.5 ° to 15 ° of e (preferred 8 ° to 12 °)
5 ° to 15 ° of f (preferred 8 ° to 12 °)
0.5 ° to 50 ° of g (preferred 25 ° to 40 °)
H 0.2mm to 0.8mm (preferred 0.3mm to 0.6mm)
In this example, the small differently structure of angle e and f.
At least working panel 4,5 can apply with wearing layer (for example based on chromium), but wherein also it is contemplated that the coating method (such as physical vapor deposition (PVD) etc.) of other types.
Therefore, in running state, end regions 10 separately abuts on the opposition working surface not shown further, wherein, at first produces linear the contact between separately end regions 10 and opposition working surface.In starting state, facilitate thus very high surface pressure and good scraping mode.
In service in other driving, structure supporting surface in the zone of free end 10, this supporting surface 10 also is narrow after the long operating time.In addition, working panel 4,5 tapering produce positive influences to oil consumption.
